Spectral sensitivity is an important parameter of color digital camera, which can be used for color correction and spectral reflectance reconstruction. In this paper, a spectral sensitivity estimated method for color digital camera based on standard color checker is studied. Under standard light source A, using the measured camera to take an image of a standard color checker, the spectral sensitivity is estimated from the camera response values of the color checker in the image, repeat the experiment under different illumination level of the same source and compare the estimated results. The experimental results show that compared with the traditional measurement methods, the estimated method in this paper can obtain higher precision spectral sensitivity and the illumination level of the ambient light source will affect the estimated results. |
